[jira] [Created] (HIVE-20730) Do delete event filtering even if hive.acid.index is not there

Eugene Koifman created HIVE-20730:
-------------------------------------

             Summary: Do delete event filtering even if hive.acid.index is not there
                 Key: HIVE-20730
                 URL: https://issues.apache.org/jira/browse/HIVE-20730
             Project: Hive
          Issue Type: Improvement
          Components: Transactions
    Affects Versions: 4.0.0
            Reporter: Eugene Koifman


since HIVE-16812 {{VectorizedOrcAcidRowBatchReader}} filters delete events based on min/max ROW__ID in the split which relies on {{hive.acid.index}} to be in the ORC footer.  

There is no way to generate {{hive.acid.index}} from a plain query as in HIVE-20699 and so we need to make sure that we generate a SARG into delete_delta/bucket_x based on stripe stats even the index is missing
